(I wonder if these are real measurements or are they not reporting the truth again? because the milk is contaminated in WA and CA what does it take to contaminate?) Any one here that can convert rad levels from picocuries? http://www.godlikeproductions.com/forum1/message1411990/pg1 | |
These are off the U.S. EPA website, just posted last night All units are in (and yet another measurement term) Picocuries per meter cubed. A picocurie is 0.037 d.p.s. or 0.03 Bq. The most common reporting unit outside the United States for radionuclide air concentrations is µBq/m3 (microbecquerels). To convert picocuries to becquerels, divide by 27 (27.027). - Filter results for Anaheim, Calif. found: Cesium-137: 0.0017 Tellurium-132: 0.012 Iodine-132: 0.0095 Iodine-131: 0.046 - Filter results for Riverside, Calif. found: Cesium-137: 0.00024 Tellurium-132: 0.0014 Iodine-132: 0.0015 Iodine-131: 0.011 - Filter results for Seattle, Wash. found: Cesium-137: 0.00045 Tellurium-132: 0.0034 Iodine-132: 0.0029 Iodine-131: 0.013 - Filter results for San Francisco, Calif. found: Cesium-137: 0.0013 Tellurium-132: 0.0075 Iodine-132: 0.0066 Iodine-131: 0.068 |

The curie (Ci) is replaced by the becquerel (Bq)* 1 kilocurie (kCi) = 37 terabecquerel (TBq) 1 curie (Ci) = 37 gigabecquerel (GBq) 1 millicurie (mCi) = 37 megabecquerel (MBq) 1 microcurie (µCi) = 37 kilobecquerel (kBq) 1 nanocurie (nCi) = 37 becquerel (Bq) 1 picocurie (pCi) = 37 millibecquerel (mBq) | Becquerel (Bq)* replaces the curie (Ci) |
The rad (rad) is replaced by the gray (Gy) 1 kilorad (krad) = 10 gray (Gy) 1 rad (rad) = 10 milligray (mGy) 1 millirad (mrad) = 10 microgray (µGy) 1 microrad (µrad) = 10 nanogray (nGy) | The gray (Gy) replaces the rad (rad) 1 gray (Gy) =100 rad (rad) 1 milligray (mGy) = 100 millirad (mrad) 1 microgray (µGy) = 100 microrad (µrad) 1 nanogray (nGy) = 100 nanorad (nrad) |
The roentgen (R) is replaced by coulomb/kg (C/kg) 1 kiloroentgen (kR) ~ 258 millicoulomb/kg (mC/kg) 1 roentgen (R) ~ 258 microcoulomb/kg (µC/kg) 1 milliroentgen (mR) ~ 258 nanocoulomb/kg (nC/kg) 1 microroentgen (µR) ~ 258 picocoulomb/kg (pC/kg) | Coulomb/kg (C/kg) replaces the roentgen (R) 1 coulomb/kg (C/kg) ~ 3876 roentgen (R) 1 millicoulomb/kg (mC/kg) ~ 3876 milliroentgen (mR) 1 microcoulomb/kg (µC/kg) ~ 3876 microroentgen (µR) 1 nanocoulomb/kg (nC/kg) ~ 3876 nanoroentgen (nR) |
The rem (rem) is replaced by the sievert (Sv) 1 kilorem (krem) = 10 sievert (Sv) 1 rem (rem) = 10 millisievert (mSv) 1 millirem (mrem) = 10 microsievert (µSv) 1 microrem (µrem) = 10 nanosievert (nSv) | The sievert (Sv) replaces the rem (rem) 1 sievert (Sv) = 100 rem (rem) 1 millisievert (mSv) = 100 millirem (mrem) 1 microsievert (µSv) = 100 microrem (µrem) 1 nanosievert (nSv) = 100 nanorem (nrem) |
